There is no independent land access to Ba Trai Dao because it is located on a remote cluster of islet outposts in the southeastern corner of Lan Ha Bay (adjacent to Ha Long Bay). To reach it, you must book an overnight cruise, take a organized day-tour boat from Tuan Chau Harbour or Ben Beo Pier (Cat Ba Island), or charter a private canoe. Once your boat anchors in the deep water nearby, you physically access the sandy bow of the beach by paddling in via kayak or riding a small tender boat directly onto the shore.
Often celebrated as one of the most pristine and exclusive natural beaches in the Gulf of Tonkin, Ba Trai Dao gets its name ("Three Peaches") from the three rounded, lush, green-capped limestone islets rising 23 meters out of the sea that shelter it. Because it is cradled inside this natural rock fortress, the emerald water is exceptionally calm, wind-free, shallow, and clear enough to spot marine life and coral reefs right below the surface. However, this paradise is fleeting: due to dramatic tidal shifts, the narrow sandy beach is swallowed entirely by the rising ocean and is only exposed and accessible for 2 to 3 hours each day.
